Benefits of technology
Effectively recovers malfunctioning intelligent batteries, reducing the number of defective batteries and optimizing recovery by stepwise resetting, ensuring accurate capacity data alignment.
Problems solved by technology
However, a CPU of an intelligent battery may hang up and become inoperable or inoperative due to ESD (ElectroStatic Discharge) which damages an electronic unit and a circuit due to discharge of accumulated static electricity.
In this case, the CPU cannot normally send various pieces of information of a battery to a system and an error due to communication failure is displayed on a LED or a screen of the system side.
However, an intelligent battery formed as a battery pack generally does not have a resetting function and therefore, there is no way that the built-in CPU recovers from the hang-up state.
In this case, it is unavoidable to handle the intelligent battery as a defective battery though the battery is not damaged in hardware and a problem on economy is also large.

Abstract
The apparatus of this invention has a resetting function for software- or hardware-resetting a battery when a CPU in the battery hangs up and becomes inoperable or inoperative to make it possible to recover the CPU of the battery from a hung state. An electrical apparatus having a body for consuming power and constituted so as to be able to connect with a battery for supplying power to the body by discharging after the battery has been charged. The apparatus has a trouble recognition mechanism for recognizing trouble in the battery and a resetting mechanism for resetting the battery in accordance with the recognition by the trouble recognition mechanism.
Description
FIELD AND BACKGROUND OF INVENTIONThe present invention relates to an electrical apparatus constituted so as to be able to connect with a battery for discharging after being charged, more particularly to an electrical apparatus capable of connecting with an intelligent battery including a CPU.Power is directly supplied from a commercial power source such as an AC adapter to electrical apparatuses such as an information terminal unit represented by a notebook-type personal computer (notebook PC), a personal unit such as a PDA (Personal Digital Assistant), various types of audio units, and a video camera and moreover, power is supplied to these units from a battery (storage battery, secondary battery, or battery) which can be used many times while repeating charge and discharge. This type of battery uses a nickel-hydrogen battery (NiMH battery) or nickel-cadmium battery that has a large capacity and a low price. Moreover, there are a lithium-ion battery having an energy density for uni...
